摘要:

在 Coifman 与 Weiss 意义下的乘积齐型空间上, 该文利用小波基引入乘积加权 Besov 空间和乘积加权 Triebel-Lizorkin 空间, 通过乘积 Calderón 再生公式和几乎正交估计建立乘积加权 Besov 空间和乘积加权 Triebel-Lizorkin 空间的 Plancherel-Pôlya 型等价刻画, 函数空间及其范数独立于正交小波基的选取.

关键词: 加权 Besov 空间, 加权 Triebel-lizorkin 空间, 齐型空间, Plancherel-P?lya 型刻画

Abstract:

On the product spaces of homogeneous type in the sense of Coifman and Weiss, this paper introduces the product weighted Besov space and product weighted Triebel-Lizorkin space based on wavelet basis, and establishes the Plancherel-Pôlya type characterizations of product weighted Besov spaces and product Triebel-Lizorkin spaces via the wavelet reproducing formula and the almost orthogonal estimation, which means that the space are independent of the choice of the orthonormal wavelet basis.

Key words: weighted Besov space, weighted Triebel-Lizorkin space, spaces of homogeneous type, Plancherel-P?lya type characterization
